CVE-2026-35001 (GCVE-0-2026-35001)

Vulnerability from cvelistv5 – Published: 2026-10-13 01:39 – Updated: 2026-10-13 01:39

Title

OpenS100 S-102 Parser Integer Overflow Heap Buffer Overflow

Summary

OpenS100 through commit daa35b contains an integer overflow vulnerability in the S-102 Bathymetric Surface parser that allows remote attackers to cause a heap-based buffer overflow by opening a crafted S-102 HDF5 file with malicious grid dimension metadata. Attackers can exploit the unvalidated multiplication of numPointsLatitudinal and numPointsLongitudinal values in the S102_VG_BathymetryCoverage::Read() function to trigger a 32-bit integer wraparound, resulting in undersized heap buffer allocation and subsequent out-of-bounds writes that lead to application crash or arbitrary code execution.

CVE-2026-22208 (GCVE-0-2026-22208)

Vulnerability from cvelistv5 – Published: 2026-02-17 14:29 – Updated: 2026-07-14 15:53

Title

OpenS100 Portrayal Engine Unrestricted Lua Standard Library Access

Summary

OpenS100 (the reference implementation S-100 viewer) prior to commit 753cf29 contains a remote code execution vulnerability via an unrestricted Lua interpreter. The Portrayal Engine initializes Lua using luaL_openlibs() without sandboxing or capability restrictions, exposing standard libraries such as 'os' and 'io' to untrusted portrayal catalogues. An attacker can provide a malicious S-100 portrayal catalogue containing Lua scripts that execute arbitrary commands with the privileges of the OpenS100 process when a user imports the catalogue and loads a chart.
